.SH "NAME"
ndb_perror \- obtain NDB error message information
.SH "SYNOPSIS"
.HP \w'\fBndb_perror\ \fR\fB\fIoptions\fR\fR\ 'u
\fBndb_perror \fR\fB\fIoptions\fR\fR
.SH "DESCRIPTION"
.PP
\fBndb_perror\fR
shows information about an NDB error, given its error code\&. This includes the error message, the type of error, and whether the error is permanent or temporary\&. This is intended as a drop\-in replacement for
\fBperror\fR
\fB\-\-ndb\fR, which is no longer supported\&.
Usage
.sp
.if n \{\
.RS 4
.\}
.nf
ndb_perror [\fIoptions\fR] \fIerror_code\fR
.fi
.if n \{\
.RE
.\}
.PP
\fBndb_perror\fR
does not need to access a running NDB Cluster, or any nodes (including SQL nodes)\&. To view information about a given NDB error, invoke the program, using the error code as an argument, like this:
.sp
.if n \{\
.RS 4
.\}
.nf
$> \fBndb_perror 323\fR
NDB error code 323: Invalid nodegroup id, nodegroup already existing: Permanent error: Application error
.fi
.if n \{\
.RE
.\}
.PP
To display only the error message, invoke
\fBndb_perror\fR
with the
\fB\-\-silent\fR
option (short form
\fB\-s\fR), as shown here:
.sp
.if n \{\
.RS 4
.\}
.nf
$> \fBndb_perror \-s 323\fR
Invalid nodegroup id, nodegroup already existing: Permanent error: Application error
.fi
.if n \{\
.RE
.\}
.PP
Like
\fBperror\fR,
\fBndb_perror\fR
accepts multiple error codes:
.sp
.if n \{\
.RS 4
.\}
.nf
$> \fBndb_perror 321 1001\fR
NDB error code 321: Invalid nodegroup id: Permanent error: Application error
NDB error code 1001: Illegal connect string
.fi
.if n \{\
.RE
.\}
.PP
Additional program options for
\fBndb_perror\fR
are described later in this section\&.
.PP
\fBndb_perror\fR
replaces
\fBperror\fR
\fB\-\-ndb\fR, which is no longer supported by NDB Cluster\&. To make substitution easier in scripts and other applications that might depend on
\fBperror\fR
for obtaining NDB error information,
\fBndb_perror\fR
supports its own
\(lqdummy\(rq
\fB\-\-ndb\fR
option, which does nothing\&.
.PP
The following table includes all options that are specific to the NDB Cluster program
\fBndb_perror\fR\&. Additional descriptions follow the table\&.
